I could replicate this on a Simple Site, but not on Atomic. Outside of Dotcom, the issue is not present either. All sites tested with Theme TT3 and Gutenberg v16.7.1

• Triaged
• @Automattic/lego I see y'all are looking over Global Styles recently - is this something y'all could have a look at as well?

I'm unfamiliar with the new property (which is about opening the image in a lightbox, and it works fine when used at an individual block level).

The GS API call contains this (among other things) as payload:

{
  "settings": {
    "blocks": {
      "core/image": {
        "lightbox": {
          "allowEditing": true,
          "enabled": true
        }
      }
    }
  }
}

The feature then adds lots of data attributes to the image element.

Typically, this kind of thing is stripped by the Dotcom KSES (although it doesn't seem to be the case here, since they work at a block level? 🤔 ).

To rule out kses, you need to compare the response to the request - if the payload you mentioned isn't echoed back in the response it is very likely to be KSES ime

@dsas Yes, that's what happens.

I tested this on a few pages and image blocks and it consistently worked.

• I toggle "expand on click" on,
• I saved
• I tested in the front end and the image expanded
• I went back to the editor, refresed the page
• Checked that the toggle was still set and it was

I'm closing this. @happychait can you please test and confirm this feature works as you expect?
